Be it known that I, EDGAR M. MATTHEWS,

a citizen of the .United States, residing at;l

Chicago, in the county of Cook'and- State of Illinois, have invented .anew and useful Improvement in Window-Sashes, of

The four rails of a square window-sash 12 like that shown in- Fig. 1,are hollow .and may be formed out of a continuous sheetthe-section foreach rail and the ends bevele at their edgeortions to '.orm theinterfit- Itingc'orners ov the sash,lsubstanta1 1yas depresent is a:

scribedof the sash of m pending application,y Serial No. 546,883, edMarch 2, 1910., Each Side sash-rail is given the configurationillustratedin Fig. 9 bybending a sec- "tion of the sheet-metal blank,referred to,

to produce the' inner vertical face 13, the 'lateral face 14, avertical. outergface 15 curved convexly at 16 to form a crown-poration,a rectangular seat 17 for the windowpane 122, cushioned as hereinafterdescribed, an outwardly-inclined vertical socket 18, and a verticalbead-seat 19. The meeting edges of 'each side-rail, as at 40, may beunited by welding or brazing. The conguration of j the upper'sash-rail," shown in Fig. 10, is produced by bending theY properblank-section to ,producethe'inner face 13",'the topface 14 the outer.face 15', the crown-portion 16', window-panel seat 17', ,incllnedsocket 18 and bead-seat 19.` The bottom sash-rail, shown in FigJ-2, isproduced by bending'the proper blank-section to 'produce the linner face132, bottom 142, outer face 152 with upper crown-portion 162 andwindow-pane seat` 172, socket 182 and beadseat 192.A The socket 182 haskey-openings formed transversely vand coincidentally through itswalls,'fas shown,'the opening illustrated at '20 in Fig: 7 whichis theinnermost one, being rovlded with lateral reycesses 20 diametricallyopposite each other,

for vthe purpose hereinafter explained.

Trough-shaped cushions 21, preferably of softrubber covered with` canvas22 to shield the rubber against'contact 4with metal, lit against theseats-17,17 and 172' provided' for them in the rails andlthese cushions,

which confine the window-pane'at its edge-l portions andserveto protectit against fracture. from vjar, shock and the like, are grooved, "asshown at 22', alongtheir seating-faces in molding them, for azpurpose yhereinafter explaine For releasably connin A in the sash, .thereby-to, aapt a broken pane to be readily. taken out and the sash-to be glazedwithout requiringlit to be removed rom the window-frame, ads areemployed those illustrated being formed hollow outoii sheet-metal fromsuitable blanks. The two beads '23,.. 23, forthe side-rails of the sashand the bead. 24 "fori the top-rail are alike, while the bead- 25 forthe lower sash-rail,

the window-pane though of "the same' configuration., 'as the.

fine the latter.

other beads, is provided in two similar longitudlnal sections, eachformed out of a sheet-metal blank 26, ,like that represented'. in Fig.8, having a notchv 27 in one end and a tongue 28 projecting from itsopposite end and in alinement with a rectangular opening 29 in the blankat a corner-portion thereof. The blank for each bead 23 and 24 is liketwo of the blanks 26 formed as a continuous strip with notches 27 in itsends and omitting the tongue 28 and opening 29, so that themanner offorming each bead will be understood from the following description withreference to bending the blank of Fig. 8.

By suitably bending the sheet-metal strip along the dotted lines 30, 31,32 and 33, the Hat base 35, the the flat back 37 o the bead are formed,and suitably bending the blank along the dotted line 34 forms thecrown-portion 38 and the fiat .face 39 of the bead, vthe edge of whichface may be united to that of the base 35 at 40 (Fig. 6) by welding orbrazing.

A blank 26 is formed in the manner described into each section of thebead 25, and the tongues 28 on their meeting edges are each bent intothe segmental shape illustra-ted in Fig. 4 to abut against each otherand constitute a semi-circular keeper 41 for the purpose hereinafterexplained. The beads are pivotally connected together at ears on theirends, like the ear shown at 42 in Fig. 6, Where the ends are caused tomeet and interft by 'the notches 27 provided -in the blank-ends andconform to the corners of the sash-frame when thebeads are adjusted inplace therein with their bases 35 against the seats 19, 19 and 192,respectively, their tongues in the sockets 18, 18 and 182, respectively,and their sides 37 bearing against t e adjacent sides of the cushions 21to con- As will bey observed, the crown-shape of the beads causes them'-to conform to and round out the crown-portions of the sash-frame rails.

To fasten and tighten the beads in place, a. key 43 is employed (Fig..2). It has a sl'ottcd screw-head 44 on oneend of a cyliindrical stem toadapt it to be turnedby a screw-driver, and it terminates at its oposite end in a comparatively thin crosscad 45.' This key is insertedthrough an opening 46' in the bottom sash-rail near the inner end of oneof thetwo sections of the divided bead 25, and through alining openings'in the socket .182 (including the recessed opening 20) and a slot in thetongue 36 therein; 'and a 'slight turn of the key will vtake its Ahead45 out of re 'stration with the recesses 20 (Fig. 7) an thus cause it toobstruct withdrawal of the key. The stem of the key carries, toturnjwith it, a 'hookshaped 'latch 47 'which extends into the bead 25through, and works-in elongated slots 48 gutter-like tongue 36 and railand base of the bead-section upon it; and on the key-stem is confined,between the hub of the latch and the adjacent wall of the socket 182, aspiral spring'49 tending to hold the key in place when turned to itsdescribed 'non-withdrawable position. By turning the key to thatposition the latch 47 enga es the keeper 4l, as shown in Fig. 4, thefgree end of the latch 'enteringy the opening 29, which is that shown inthe blank 26; and thus the beads are locked in place, the sections ofthe bead 25 being tightened by the spring-action of the key ,against theadjacent' cushion 2l and compressing it,

thereby narrowing the groove 22 with the effect of mutually tighteningthe cushions and edges ofthe window-pane against each per and side beadsto enable them to be removed, as for taking out of the sash a fracturedwindow-pane and inserting a new one, which is then to be fastened in thesashframe by adjusting the beads in placesand .securing them with thekey 43.

What I claim as new and desire to secure by Letters Patent isn l. In awindow-sash, the combination of a frame comprising rails provided withwindow-pane seats, beads coperating with said seats to confine the pane,one-of said beads comprising longitudinal alining sections,l andkey-operated means cooperating with a frame-rail and said sections toreleasably lock the sections'together. 2. In a window-sash, thecombination of a frame comprising rails provided with Window-pane seats,beads coperating with said seats to conne the pane and pivotallyconnected end to end, one of said beads comprising lon itudinal alining.sections, and key-operate means eoperating with a frame-rail and saidsections to releasably lock the sections together. 3. In a window-sash,the combination of a frame comprising rails provided with window-paneseats, trough-like cushions on said seats for confining a pane at itsedges, said cushions being grooved along their seating faces, beadscoperating with said cushions to confine them, and key-operated meanscooperating with a .frame-rail and the bead thereon to releasably securethe beads in place 4. In a Window-sash, the combination of a i framecomprising rails provided with win-v dow-pane seats, trough-hke-cushionson' said seats for confining a pane at its edges, said cushions beinggroovedalong their seating edges, beads coperating with said cushions toconfine them and flexibly connected at their ends, one of said beadsycomprising 13C longitudinal alining sections, and key-operated meanscoperating `with a frame-rail and said sect-ions thereonto releasablylock the sections together.

5. In a Window-sash, the combination of a frame comprising railsprovided With window-pane seats and bead-seats With interposed sockets,beads removably fitting against said seats and having tongues extendinginto said sockets, one of said beads comprising longitudlnal aliningsections with a keeper on their adjacent ends, a key Working -in theframe-rail provided with said bead-sections and passing through thesocket and tongue in its path, said key having a head on its inner end,and a latch on the key extending into the adjacent beadsection to engagesaid keeper.
